Zapping the spine and brain together may restore hand control after paralysis

This study tests whether pairing brain stimulation with spinal cord stimulation can make hand exercises more effective for people with chronic cervical spinal cord injury. The idea is that synchronized stimulation strengthens nerve circuits, improving hand muscle responses. Up to 12 participants will undergo many sessions over 6-10 months to find the best stimulation settings for each person. The goal is to improve hand function, which is a top priority for those with this injury.
